Description of the Related Art Generally, when vertical vibration is applied to a powder or granular material (a powder or granular material layer) filled in a predetermined container, the powder or granular material layer flows in the container. It is known that the state of this flow changes variously depending on the frequency and amplitude of the applied vibration. Regarding the behavior of the vibration flow caused by the relative movement between the granular material layer and the container, as shown in the flow pattern of FIG.
First, the movement of the granular material occurs as in the pattern B and the surface of the granular material layer inclines, and then a circulating flow (convection) from the center of the powder layer toward the container wall as in the pattern C1 occurs. At this time, the surface of the vibrating granular material is flat when the speed of the circulating flow is slow, but when it becomes active, a slight swelling occurs on the surface of the granular material. When the centrifugal effect is further increased, the direction of the circulation flow is reversed as in the pattern C2, and then the local circulation flow is generated in the powder layer as in the pattern D, which is peculiar to the surface of the granular material. Waves are said to appear.

On the other hand, the response of the granular layer to the vibration amplitude and frequency has not been fully analyzed yet,
Since oscillating flow is also a phenomenon that is difficult to predict, there is no guarantee that all the particles in the container will be uniformly dispersed by the circulating flow and appear on the surface of the particles. The circulating flow is not a high-speed one suitable for various powder and granule treatments such as mixing, reaction, and surface treatment.As a processing device that directly uses the vibrational flow of the powder and granules, a discharge device, a sieving device, a transportation device, etc. However, in reality, the range of use is limited. In recent years, there has been a demand for high-speed powder particle processing technology and uniform processing.
It has been desired to develop a vibrating and fluidizing device for powders and granules, which can perform processing such as mixing, reaction with spray gas, coating on the surface of powder and granules, vapor deposition, and the like, and can perform these processings in a short time. There is known a vibration mill that crushes powder particles by a unique circular vibration, but this one gives a circular vibration locus to a spherical medium in a cylindrical container, The spherical medium is made to collide with the inner wall so as to pulverize the granular material between the inner wall of the container and the spherical medium, and from this point of view, the circulating flow of the granular material itself is not used, It cannot be adopted.

That is, the container 2 and the sphere 401 are a set of different kinds of vibrating bodies 2 and 4 which give different vibrations to the powdery or granular material 3 to be processed. By virtue of the cooperative relationship in which the sphere 401 that constitutes the other enjoys the vibration, the powder and granules 3 are fluidized by the joint vibration action of the two.

As the vibration device 1, an electric micro-exciter (MES451) manufactured by Akashi Co., Ltd. was used. (1) Experimental example in which spheres are used as the vibration medium In the case of treating the powdery particles 3 using the spheres 401,
Glass beads having an average particle diameter of 5 mm are used as the spheres 401, and polyethylene particles (white) having an average particle diameter of 5 μm are filled as the powder particles 3 into the container 2 to a height of about 1 cm to form a powder particle layer. Frequency 1-10 kHz, amplitude 0.1
I gave a vibration of 10 mm. Then, the behavioral state of the oscillating flow is shown in FIG. 2 (A) as a drawing substitute photograph, and the state explanatory view is shown in FIG. 2 (B). Figure 2 (B)
2A is the same as the one shown in FIG.
No. 01 is subjected to contrast and light / dark tone color processing to clarify the flow state.

After 2 to 3 seconds, the behavior again appeared on the surface. This behavior is observed by observing the flow behavior for mixing and dispersion from a state in which a small amount of colored particles (red) having an average particle size of about 100 μm are put on the central part of the surface of the granular material layer. In the initial vibrating stage, which is a relatively small exciting force, the colored particles are instantly and uniformly dispersed in the entire area of the container 2, and a good circulation flow that appears again on the surface is generated. Have been confirmed. In this way, even if the powder or granular material has different physical properties (particle size, density, etc.),
It was found that they were uniformly mixed and dispersed in a short time.

ないことが確認された。Next, when the vibration force was gradually increased and the behavior in the high frequency region was observed, as shown in the drawing-substitute photograph of FIG. 2 (A), the particles 3 were violently moved upward from between the spheres 401. The flow behavior of mist-like ejection was confirmed. Figure 2
Describing based on (B), the powder and granules 3 are the spheres 401
In the region where the slab was laid, an intermittent jet flow 301 was confirmed everywhere in a state where the hot water boiled in the initial state of jetting, and when the exciting force was further increased, it continued in the central region of the container 2. It was confirmed that the jet flow 301 was a normal jet flow and that the jet flow 301 was an intermittent jet flow in the outer peripheral region. At that time, the spheres 401 are randomly rotating, and the powder particles 3 are repeatedly ejected from the gap surrounded by the adjacent spheres 401 and moved to the bottom side of the container 2 and are scattered on the side wall surface of the container 2. The powdery granules 3 exhibited a behavior of moving from the laid peripheral region of the sphere 401 to the bottom side of the container 2. Similarly,
As a result of comparative observation of the conventional vibrating flow behavior that does not use the sphere 401, it takes about 1 minute before the colored particles 3 gradually cover the colored particles 3 and cover all the colored particles and become invisible from the surface. It took a while. Further, it was confirmed that even if a vibration in a high frequency region with an increased excitation force is applied, it does not appear again on the surface, and a good circulation flow for dispersion and mixing is not generated.

動を示した。(2) Experimental example using a perforated plate as the vibration medium Under the conditions of the above experimental example (1), the perforated plate having a hole diameter of 2 mm and a plate thickness of 0.5 mm is made of stainless instead of the spherical body 401. 402 was used to apply vibration to the granular layer. Then, the behavior state of the oscillating flow is shown in FIG. 3 (A) as a drawing substitute photograph, and the state explanatory view is shown in FIG. 3 (B). FIG. 3 (B) shows the flow state of the powder / granule jet flow 302 and the perforated plate body 402 by applying contrast and light / dark tone color processing to that of FIG. 3 (A). First, when an exciting force is applied to the granular material 3 in the container 2 by the vertical vibration of the vibrating device, the granular material existing on the surface of the granular material layer instantly moves to the bottom of the container 2, The same behavior as that of the above-mentioned experimental example (1) was exhibited in which the surface appeared again after 3 seconds.

A violent columnar flow behavior was confirmed. The state will be described based on FIG. 3 (B). In the region in which the perforated plate body 402 is installed, the powdery or granular material 3 is
The jet flow 302 was confirmed to be intermittent everywhere, and when the vibration force was further increased, it was confirmed that the jet flow 302 was formed into an intermittent jet flow 302 with the entire area of the perforated plate being integrated. . At that time, the powdery particles 3 are ejected from the holes in the lower surface area of the perforated plate at a stroke, and the powdery particles 3 are repeatedly moved to the bottom side of the container 2 and scattered on the side wall surface of the container 2. The granules 3 showed a behavior of moving from the laid peripheral region of the perforated plate body 402 to the bottom side of the container 2. Furthermore, the hole diameter is 1 cm
When the ejection state was confirmed using the perforated plate of No. 3, it was confirmed that the ejection was from the circumferential region of each hole. In addition, the perforated plate body 402 may have a mesh shape. Further, in the above experimental example, it was confirmed that the jet flow was reduced when the flow environment was gradually reduced, but it was found that the apparatus configuration of the present invention can be applied even under reduced pressure (in a reduced pressure container).

In order to obtain the vibrating flow necessary for processing the particulate material such as dispersion, mixing, and drying of the granular material, a vibrating force that ejects the granular material from the vibrating medium is applied to the granular material layer. Even if it is not given, most of the powders are instantly and uniformly dispersed,
It is possible to obtain a good circulating flow that reliably appears on the surface of the granular material layer without using a fluid medium such as air or gas, or a solid medium such as an impact ball, and only by the circulating flow due to oscillatory flow. It can be processed directly. In addition, its circulation behavior enables a variety of circulating flow control, such as spraying the surface of the granular material layer from a smooth surface to a scattered or columnar shape, and the spray gas can be sprayed only to the sprayed granular material. It is also possible to carry out complex treatments such as reaction with the like, coating, vapor deposition, etc., and the overall mechanical structure does not become particularly complicated, and miniaturization can be facilitated.
